That compares well with just 20 per cent for all mobile phones and 48 per cent for other smartphones.

As iPhones come with flat-rate data plans, satisfaction will most likely be drawn by online advertisers keen to get their products in front of key demographics.

Still a small group

However, there is a caveat – as comScore points out: "It is ... important to note that while nearly all iPhone owners are consuming mobile media, the device is in the hands of only 2 per cent of mobile phone users in the UK."

As well as high web usage, iPhone owners appeared to use email a lot – 75 per cent did so, compared with just 35 per cent of owners of non-Apple smartphones.

Still, that begs the question of why on Earth those folk bothered buying smartphones at all.

It's an iPod too, you know

Almost as puzzling is the revelation that 66 per cent of iPhone owners used it to listen to music. We're assuming that the left-out 34 per cent are blissfully unaware that it's also an iPod.
